Abrus precatorius

  

Abrus precatorius, commonly known as rosary pea or “Olinda” in Sri Lanka, is a slender, climbing plant recognized for its striking red and black seeds. Native to tropical regions, it is often found growing along fences, forest edges, and in disturbed areas throughout the island.

The plant produces small, purple flowers and distinctive seeds that are used in traditional jewelry and cultural artifacts. Despite their beauty, the seeds are highly toxic due to the presence of abrin, and must never be ingested or broken, as even a small amount can be fatal if improperly handled.

In Ayurvedic and folk medicine, the seeds and roots are used with caution after careful detoxification to prepare remedies for hair care, skin conditions, and pain relief. The plant also serves as a natural nitrogen fixer, benefiting soil health in agroforestry systems.

Abrus precatorius grows well in warm, tropical climates and is common in lowland areas. It flowers during the dry season and is valued for both its ornamental appeal and traditional medicinal uses, although strict handling precautions are necessary due to its toxic nature.
